We are currently running SQL2016 SSRS on a SQL 2012 R2. We just updated the SSRS 2016 to SP1 CU2 as we applied the same update to our 2016 SQL Servers. After we applied the updates we are now receiving errors on some of the reports. The error is as follows:
Could not load mobile report
The report may be misconfigured, the data may not be available, or the server version may be unsupported.
If you look in the logs you see this error every time you generate the report error:
ERROR: [0qqkbnx0]: XSRF Failed (ExpiredTokenHeaderTimestamp)
Does anyone have any ideas on how to resolve this issue.
